 Posted: Thu Feb 21, 2013 11:22 am Post subject: [SOLVED]Can't find grub2 via emerge when buliding new system |
 |
|
Hi all;
I'm building up a new server using the current version of the Live DVD to bring the machine up so it can download and build from Stage 3.
I've used parted to partition the drives with GPT.
All was going well, until it came time to emerge Grub2. It's nowhere to be found! The only results that came back were for the old version of Grub, namely 0.97, and that of course won't work on this disk.
Can anybody tell me what's happened? How do I get Grub2 onto the system so I can finish the build?

I've never needed to use grub2,but it is in portage although masked.
So in order to install it you'll have to unmask it.

That's odd: I had built another machine a few weeks ago, and Grub2 was there without the need to do anything else apart from install it, and everything went off without a hitch.
How do I unmask it if I can't even see it in the emerge list? |

Well, first of all, if you haven't already, emerge gentoolkit, which contains equery. With it, you can see all available versions which, as of this writing, are: | Code: | $ sudo equery list -p grub

Inside the second set of brackets the tilde character (~) indicates which versions are masked, the dash which versions are hard masked. Regarding unmasking, I'll refer you to the Mixing Software Branches chapter of the Handbook.

@666threesixes666, the philosophy, consciously applied (I believe) by both Gerard and myself, is not to spoon feed, but to teach the OP where in the Gentoo documentation to learn what he needs in order to proceed. Spoon feeding Gentoo doesn't work well in the long run.
I'll also just give a friendly first warning that name calling is against the Forum Guidelines.

if my lovely reported post fails, its because portage needs updated to pull in grub2 ebuilds...
again as root
(then run the reported post's emerge grub command) |

666threesixes666 grub2 would still be masked.
So who's the noob here?

sys-boot/grub
Installed versions:

| I tried unmasking as suggested in the various posts, all to no avail. I just couldn't get Grub2 to appear, so I gave up and just used Grub legacy with the fdisk boot flag workaround. System now boots. I take it there were some problems with Grub2 if it's now masked. |

shouldnt be
try running this and see if you see similar output:
| Code: |
# emerge -pv =sys-boot/grub-2.00-r2
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild NS #] sys-boot/grub-2.00-r2:2 [0.97-r13:0] USE="nls -custom-cflags -debug -device-mapper -doc -efiemu -libzfs -mount -sdl -static -truetype" GRUB_PLATFORMS="-coreboot -efi-32 -efi-64 -emu -ieee1275 -multiboot -pc -qemu -qemu-mips -yeeloong" 0 kB
Total: 1 package (1 in new slot), Size of downloads: 0 kB
The following mask changes are necessary to proceed:
(see "package.unmask" in the portage(5) man page for more details)
#required by =sys-boot/grub-2.00-r2 (argument)
# /etc/portage/package.mask/grub2:
=sys-boot/grub-2.00-r2
NOTE: The --autounmask-keep-masks option will prevent emerge
from creating package.unmask or ** keyword changes.
* IMPORTANT: 1 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.

NB: i dont know why the superflous cat'ing until EOF, when `echo` will do. E.g. echo '>=sys-root/grub-2' >> /etc/portage/package.unmask

Now THAT shows it. OK, will remember this for next time, if it doesn't pop up by itself. Thanks. |

Should also work, if you take a look at eix or whatever else you can see it is slot 2, just saves a little typing  . |

yip, standard 'emerge sys-boot/grub' is only going to show you the latest grub version that isn't keyworded or masked in some other way
i actually use 'eix' to show me all versions of a package in portage; there are other ways, but this is the quickest for me
| Code: |
emerge -v eix
eix-update
|
then
| Code: |
vunnable ~ # eix sys-boot/grub
[I] sys-boot/grub

from that, i can see that grub-2.00-r2 exists, but is masked. If I don't understand the letters or characters, I can try to emerge that specific version to see *why* it's not showing up when i do a normal emerge, by prepending the '=' to the full package atom:
| Code: |
vunnable ~ # emerge -pv =sys-boot/grub-2.00-r2
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild NS #] sys-boot/grub-2.00-r2:2 [0.97-r13:0] USE="nls -custom-cflags -debug -device-mapper -doc -efiemu -libzfs -mount -sdl -static -truetype" GRUB_PLATFORMS="-coreboot -efi-32 -efi-64 -emu -ieee1275 -multiboot -pc -qemu -qemu-mips -yeeloong" 0 kB
Total: 1 package (1 in new slot), Size of downloads: 0 kB
The following mask changes are necessary to proceed:
(see "package.unmask" in the portage(5) man page for more details)
#required by =sys-boot/grub-2.00-r2 (argument)
# /etc/portage/package.mask/grub2:
=sys-boot/grub-2.00-r2
NOTE: The --autounmask-keep-masks option will prevent emerge
from creating package.unmask or ** keyword changes.

and there you are; it tells you why that specific version is blocked
